Optimal conditions and selectivity of extraction of a mixture of nine REM3+ions with 0,5 mol / L solution of neocarboxylic acid hydrazides of the C15–C19fraction from sulfuric acid media and the ratio of the phases Vо: Vwwere determined. The capacity of the organic phase relative to individual REM3+from media containing 0,3 mol / L H2SO4was determined.
